UNITED STATES PAT NT OFFICE.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed July 14,1905. Serial No. 269,713. I

To all whom it may concern:

Be it known that I, ERNEST A. PANNIER, a cltlzen of the United States,residing at Chicago, in the county of Cook and State of Illinols, haveinvented new and useful I'm rovements in Water-Heaters, of which the ihllowing is a specification.

This invention is a waterheater ada ted particularly for use inconnection with a ctwater or steam heating system, and provides meanswhereby the heated water or steam used in the heatin system may beutilized for heatin water or the Water-supply system of the ouse or'building. The invention is particularly characterized by a cheap andimproved construction of the heater, as will more fully appear from thefollowing description.

In the accompanyin drawings, Figure 1 is a s1de elevation of the eaterconnected to a tank and boiler and illustrating one use to whichtheheater may be put. Fig. 2 is a central vertical section of the heater.Fig. 3 is a section on line 3 3 of Fig. 2. v

Referring specifically to the drawings, 6 in-. dlcatesa steam orhot-water boiler of any desired construction, and in the utilization ofthe device for domestic purposes it is intended that this boiler shallbe a part of the heatmg system. The boiler is connected b pipes 7 and 8to the water-heater, ashereina ter described, these pipes beingcontrolled by valves 7 and 8 and thewater-heater is connected by pipes 9and 10 to the water-tank '1 1, which is a part of the water-supplysystem for the'house or other building.

ing 12, which mafi The water-heater consists of an outer casconvenientlybe made of iron pipe of suita le diametersay three or four inches: Thisipe is threaded at both ends to screw into the upper and lower headers.The upper header consists of a cap 13, into the top of which the pipe7is screwed, and the rim -of this ca is interiorlyl threaded to receive acircular plate 14, whic has a depending rim 15 interiorly threaded toreceive the upper end of the pipe 12. The plate 14 has a series of holes16, preferably arranged around a central cone 17, which acts as adistributer. The holes 16 receive the ends of the interior pipes 18,which are expanded there-in.

' The lower header 19 s cast in one iece and has a central circularchamber 20, t e top of which is provided with taps 21, corresponding tothe holes 16, and the lower ends of the pipes 18 are screwed inthe saidtaps. The bottom of the header 19 extends out beyond the side wall ofthe chamber 20 and is provided with an annular flange 22, which 1sspaced from the side wall of the chamber 20 and is interiorly threadedto receive the lower end of the outer pipe 12.

The i es 9 and 10 are ta ped into the side Wall 0 t e pipe 12, and althe connectlngpipes are provided with the necessary unions, elbows,'&'c.- The cap 13 is or may be provided with lugs 23 ,whereby the heatermay be hung from-a beam or joist, or the heater may be supported frombelow by any suitable stand.

In assembling the parts the header 19 and plate 14 are screwed onoppositeends of the Y outer pipe 12. The inner pipes 18' are theninserted and screwed into the taps 21 and then expanded over the plate14. The cap 13 is then screwed on and the proper connections made. l

The hot water or steam from the boiler 1s supplied through the pipe 7and circulates down through the pipes 18 and the headers and backthrough the pipe 8 to the boiler. The water to be heated circulates fromthe tank through the pipe 10 and up through the outer tube 12 and aroundthe inner tubes 18 and back to the tank through they pipe 9 and isheated by radiation from the headers and the ipes 18. p

ithout material modification the apparatus may be used as a cooler forwater or other fluids by roviding a circulatlon of cold fluid through te device.

What I claim as new, and des1re to secure by Letters Patent, is-

A water-heater comprising an outer cylin-. drical casing having inletand outlet pipes,

headers on opposite ends of the casing, connecting-pipes between theheaders, within the casing, one header having two parts, one

consisting of a plate havin holes forthe sald connecting-pipes and a teaded ring into which the end of, the'casing is screwed, and the otherpart consisting of a cap screwed onto the'plate.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ERNEST A. PANNIER.
